				Wonderful presentation Mr.Ahmed! 
  
Allow me to add a little piece of information concerning the inversion.  
  
With "ONLY WHEN", the inversion comes in the second clause. 
  
e.g. (mentioned in the Self-Evaluation Guide in the rewrite section P.45 Ex. 34. and answered wrongly on P.61) 
  
You will understand what true responsibility is only when you become a parent. 
  
WRONG ANSWER P. 61 
  
Only when do you become a parent, you will understand what true responsibility is. WRONG ANSWER 
  
THE CORRECT ANSWER: Only when you become a parent, will you understand what true responsibility is. 
  
The same rule here applies also with: only if / only after 
  
But we cannot apply this rule with: only then.  
Only then is followed by direct inversion. 
  
Best Regards!
